A conformal mapper written in Python; a small exercise from 2018.
- Install numpy
- Install pygame
- Download the repository to wherever you'd like
Run python conformal.py IMAGE [-t] where IMAGE is a path to the image you'd like to transform and the -t option causes the resulting image to be tiled. If no arguments are provided, conformal will default to using the image think.png provided in the same directory as conformal.py.
On the command line, you determine the transformation by entering any valid Python expression with the variable z. You have access to the cmath and numpy libraries, so you can really let your imagination run wild. An example transformation is 1/z if not z == 0 else 0, which denotes the reciprocal transformation (while accounting for a possible division by zero). Another example is cmath.sqrt(z). The sky really is the limit.
Clicking on the image displayed will switch between the original image and the transformed image, allowing you to better understand what the transformation is doing.
To quit, simply type quit on the command line in place of an actual expression.
